 *ksrates* is user-friendly command-line tool and [Nextflow](https://github.com/nextflow-io/nextflow) pipeline to compare paralog and ortholog *K*<sub>S</sub> distributions derived from genomic or transcriptomic sequences. *ksrates* estimates differences in synonymous substitution rates among the lineages involved and generates an adjusted mixed plot of paralog and ortholog *K*<sub>S</sub> distributions that allows to assess the relative phylogenetic positioning of presumed WGD and speciation events.

 *ksrates* is an open-source tool offering a rate-adjustment strategy that brings all the distributions to a common *K*:sub:`S` scale by compensating for the differences in synonymous substitution rates relative to the species of interest, the focal species. The final mixed plot produced by *ksrates* features rate-adjusted positions of the ortholog *K*:sub:`S` estimates of species divergence times that help to clarify the phylogenetic placement of WGDs inferred in the focal species.
